Comments. The notch separating the lower mandibular tooth is quite unusual. At first sight, it is difficult to determine if the notch is triangular or semi-circular, as observed in the CAYENNENSIS-Group. It is so difficult that for a time we supposed that the L. manaica specimens was a new species of the CAYENNENSIS-Group. In one specimen there is variation between the right and left mandible. In one of them, the notch is narrower and sharply triangular, well angulated, while in the other the notch is larger and similar to a semi-circular notch. Both Bouček (1974a) and Cooperband et al. (1999) speculated that L. manaica and L. bulbiventris Cresson, 1872 were female and male, respectively, of a single species, i.e., synonyms. In this case, by the principle of priority, the name L. bulbiventris would be the valid one. Unfortunately, none of the authors formally proposed the synonym, and since we did not have access to the type material of these species, nor male specimens, we retain these species separately in the identification key.
